Can anyone tell me if they use these pozzolans in wet cast .I can by pozzolan Portland but I am not quite sure what the amount to Portland is. Does anyone use pozzolan portland for there gfrc face coat? I am trying to use Gore's GFRC mix design and have never done GFRC or seen it done.I also am wondering if I can use a frits pac plasticizer  and is the forton vf 774 a must.

Brandon is very correct. I used up to 25% flyash in my wet cast and up to 22% of micron HS in my GFRC. I used in in the face coat always and in the back coat sometimes. the 3 advantages for micron hs are 1) helps prevent secondary efflorescence 2) makes the mix more sticky, good for vertical (this is when I would use it in the back coat) 3) recycled content.

Follow the mix design and use the required elements. if your baking a cake, you would not replace the flour with sugar just because it is white and powdery and easier to get. If the recepie says use this flour, for this mix to work, then why try to re-invent the wheel. Some of us have already done the footwork, use our knowledge and go make col concrete.

Off topic.....It is my opinion that if people stopped worrying about tweaking their mix and worked more on marketing, branding and business, they wouldn't be struggling so much. just a thought.
Thanks guys I appreciate the info ,it is not my desire to make my own path when the path is already paved and I really appreciate people like you two that have paved the way it is a privilege to get advice from you guys. my problem is the materials are not always readily available. I talked to my local concrete experts (Border supply) about vitro pozzolans and they acted like I was speaking Chinese . For me to order the vitro minerals from expessions it is $30 a bag and $50 in shipping for one bag. I work and live in a spiritual community that is a nonprofit organization so as much as I would love to go out on a shopping spree it is not always realistic for me. Don't get me wrong every part of my work does not revolve around money nothing in my community does but the world we live in definitely does . My work is labor of love I am a contractor but I donate %100 percent of the proceeds to my intentional community ,it is a beautiful thing.
Josh, I would love to know more about your community!! Give me a call sometime so we can chat. thanks - T

Actually remik I am a human being I don't claim to be a democrat, republican, liberal ,communist, nor do I claim a religion. When you claim to be a Christian Buddhist Catholic or any other fundamentalist you automatically have a outlook as if you have a bigger picture than anyone else. I don't claim to have a all encompassing picture and know I am not a agnostic either. My goal is not to be cheap and I am not trying to eliminate ingredients from this mix but as I said this is uncharted water for me. My goal is to have a good understanding of all trades in that I believe there is truth in all religions and politics and if I can take the truth and apply it I will have a more full life, as if I can take the truths from as many aspects of building ,art, architecture ,engineering and anything else I can think of in this arena I will be able to produce a paradigm shift in building and living and that my friend is true sustainability. I believe that if the planet we live on does not start shifting in this direction we will be f***** if not already. I personally would like to start building thin shelled GFRC structures and use closed cell urethane insulation on the exterior and GFRC on the interior for radiant mass and do this in free form structures .
Josh, we need to talk!! we have some similar goals. I look forward to hearing from you.

Remik, Cool concrete. Col is Mexican slang for cool. And yes, people are struggling.

I love this forum to each is his own thanks chad I appreciate it. If we all got along it would be a perfect world and if I had 1/8 the wisdom as I do pride I would be a master at every thing and transcended this plain of existence.
